Regularity Properties of Solutions of a Model for Morphoelastic Growth in the Presence of Nutrients in One Spatial Dimension

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT Regularity properties of solutions for a class of quasi‐stationary models in one spatial dimension for stress‐modulated growth in the presence of a nutrient field are proven. At a given point in time the configuration of a body after pure growth is determined by means of a family of ordinary differential equations in every point in space ...

Beyond nocardioform: Transcriptionally active microbes and host responses in equine mucoid placentitis

Equine Veterinary Journal, Volume 58, Issue 2, Page 601-618, March 2026.
Abstract Background Nocardioform placentitis (NP) is an understudied form of equine placentitis historically attributed to nocardioform bacteria, yet it remains uncertain whether these organisms are the sole pathogens involved. Objectives To elucidate the pathophysiology of NP and the host–pathogen interaction. Study Design In vivo clinical multi‐omics

Fixed point results for generalized convex orbital Lipschitz operators

Demonstratio Mathematica
Krasnoselskii’s iteration is a classical and important method for approximating the fixed point of an operator that satisfies certain conditions. Many authors have used this approach to obtain several famous fixed point theorems for different types of ...

A Jacobian‐Free Newton‐Krylov Method for Cell‐Centred Finite Volume Solid Mechanics

International Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.
ABSTRACT This study proposes a Jacobian‐free Newton‐Krylov approach for finite‐volume solid mechanics. Traditional Newton‐based approaches require explicit Jacobian matrix formation and storage, which can be computationally expensive and memory‐intensive.

Towards Rapid Calibration of Bioprocess Quantification Models Using Single Compound Raman Spectra: A Comparison of Four Approaches

Biotechnology and Bioengineering, Volume 123, Issue 2, Page 324-336, February 2026.
ABSTRACT In‐line Raman spectroscopy combined with accurate quantification models can offer detailed real‐time insights into a bioprocess by monitoring key process parameters. However, traditional approaches for model calibration require extensive data collection from multiple bioreactor runs, resulting in process‐specific models that are sensitive to ...

Existence and Stability of Solutions for p-Proportional ω-Weighted κ-Hilfer Fractional Differential Inclusions in the Presence of Non-Instantaneous Impulses in Banach Spaces

Fractal and Fractional
In this work, we introduce a new definition for the fractional differential operator that generalizes several well-known fractional differential operators.

The Neural Blueprint of Novelty: A Meta‐Analytic Dissection of Active and Passive Novelty Processing Networks

Brain and Behavior, Volume 16, Issue 2, February 2026.
An ALE meta‐analysis of fMRI studies reveals a shared novelty‐responsive core (bilateral MTL, IFG, medial frontal cortex). Explicit, task‐relevant processing (active) emphasizes left prefrontal/motor and right MTL, whereas incidental, task‐irrelevant processing (passive) emphasizes salience regions, indicating task‐dependent spatial convergence within ...

On the solution of Steinhaus functional equation using weakly Picard operators

Filomat, 2011
In this paper we obtain existence results regarding the solutions g of a Steinhaus type functional equation of the form g(x)+ g(f(x))= F(x), under the significantly weaker assumption that f is a weakly Picard operator. The solutions are given in terms of sums of either convergent series or divergent series but summable by some method of ...
